PANEL CONSTRUCTION.

Learner,

To all whom it may concern 7 Be it known that 1, Emma C, DllTMAlI, acitizen of the United States, residing at i l illiamsport, in the countyof Lycoming and State of Pennsylvania,have invented certain new anduseful Improvements in Panel Constructions, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a method of constructing panels used forornanienting walls, churchpcws and the like, and for various otherpurposes; the objectbeing toconstruct a paneloi' strips of stockmaterial assembled in such a manner that the cost of forming acute andobtuse angles, is greatly reduced.

Another and further object of my invention is to produce a panel inwhich the stock material employed in the construction of the same, isall arranged with the grain running the same way, so as to givethecomplete panel the effect or being constructed of a single piece.

Another and'iurther object of the inven tion is to produce a panelout oia series of rabbeted stock pieces assembled in such a manner that acuteand obtuse angles are formed at the junction of the stock pieces whicheliminates the hand-work now employed in producing a panel of thisconstruction, thereby greatly reducing the cost of production andproviding a panel in which the appearance of the same is not changed, inany way.

Another and further object of the invention is to construct a panel ofrabbete'd strips which when assembled, and secured by glue or otheradhesive material, form a panel with acute and obtuse angles at thejunction of the stock pieces, these stock pieces being cut to thedesired shape by machinery before being assembled the cen tral stockpiece having openings formed therein to allow the milling tool to coinplete the desired design therein.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings- Figure 1, is a plan view of a series of stock pieces inposition to be assembled to term the complete panel;

Fig. 2, is a plan view of the complete panel showing the central piecesmilled to produce a Gothic design;

Fig. 3, is a detail plan view of a central portion of the panel,constructed of the stock pieces, showing in dotted lines, the centralportion milled to the desired design; and i l i Fig. l, is a transtersesection through a series of stock pieces arranged to be as sembled.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

In carrying out my invention :to produce a Gothic panel, I employ sidestock pieces 1 and 2, which are provided with rabheted inner edgesadapted to receive the ralbbeted edges of top and bottom stock pieces 3and l. herein shown having their opposite edges rabbeted to join withthe side pieces 1 andil.

The top pieces 3 are cut on the are of a irele and their inner edges arealso rabbeted to lit a central stock piece 5, the opposite sides ofwhichare rabbeted to correspond with the top pieces 3 as clearly shown,so that when the panel is formed by the central piece, side pieces andtop and bottom pieces, the top of the panel will be curved and thebottom of the panel will be straight.

The bottoms of the top pieces are provided with concaved faces 6 and thetop of the bottom piece at is provided with a beveled face; it, ofcourse, being understood that the formation of these pieces will bevaried according to the Gothic design desired, but it will be noted thatwhere these pieces join the central piece and side pieces, an acuteangle is formed which eliminates the handwork now employed for formingthe angles at these points.

Arranged between the side pieces 1 and 2 are the central stock pieces 8and 9, the tops of which are beveled and the side edges rabbeted to fitthe rabbeted faces of the side pieces and central piece, these centralpieces 8 and 9 being formed with openings as shown, so as to allow themilling tool to be inserted in order to cut away the central portion ofthe panel, thus formed, to produce a Gothic design as shown in dottedlines in Fig. 3.

In constructing the panel, the stock pieces 1, 2, 3, 4;, 5, d and Q arecut to the desired length with their ends at the desired angles, asshown in Fig. 1, and these pieces are I dotted lines, as shown in Fig.3, to produce the central Gothic effect.

Previous to myinvention, Gothic panels were constructed from a singleplank which was first cut out to approximately the design desired, andthe panel was then milled by a milling tool, but in forming the acuteand obtuse angles, it was necessary that these angles be formed by hand,and,,theref0re, the cost of producing a panel was greatly increased,while with my construction, all of these angles formed, are by thejoining of stock pieces together.

\Vhile I have shown and described a particular design for panels, I donot wish to limit myself to any particular design, the main object to beaccomplished being to produce a panel out of a series of pieces of stockmaterial cut to the desired shape and having rabbetcd edges which areadapted to be united in such a manner that a panel can be constructedwith acute and obtuse angles without employing hand labor foraccomplishing this style of panel.

I claim V p 1. An improvement in the art of producing panels comprisinglongitudinal and transverse elements similar to stiles, rails, mullions,and the like-in whichthe inner, adjacent or component faces are moldedorshapedto present substantial relatively salient portions, (previouslyformed by carving of an integral block,) which improvement 7 consists inmaking those portions which lie transversely to the others separatetherefrom and making the molded contour of one set of parts as thestiles or mulllons continuous throughout the lengths of such parts andmaking the end surfaces of the parts of the other set as the rails, acomplement of such molded contour, and fitting each rail and stile orInullion to form a de sign. V

2. An ornamental open work paneliformed of separate longitudinally andtransversely disposed stock pieces having what are, in the finishedproduct, their inner or confronting faces molded throughout-their lengthto present substantial salient portions, the end surface of thetransverselydisposedpieces conforming to the molded contour of thelongitudinal pieces. 7 In testimony whereof I hereunto afiix mysignature in the presence of two witnesses.
